摘要
讲述了一种基于 USB的 12 b高速数据采集与信号分析系统的设计 ,设计中采用了 FPGA (可编程逻辑器件 )实现时序逻辑信号的控制 ,从而整个系统的设计具有很大的灵活性。该系统在 Windows2 0 0 0环境下的驱动程序及用户应用程序采用的是 Visual C++语言实现的 ,而固件代码则是用 C语言实现的。系统具有低成本、高性能的特点 ,能够广泛应用于测控、信号分析等多个领域。
The design of a 12 b data acquisition with high speed and signal analysis system,which is based on USB(Universal Serial Bus), is introduced in this paper Due to the use of FPGA to control the logical time sequence signal in the design, this method has great agility The driving program,which is used for Windows 2000,and the application program of the system are realized in Visual C ++ language And the firmware codes are programmed in C language Because it has a low cost and a high performance,the system can be widely used in such fields as measurecontrol, signal analysis,and so on
